Coming from the 8-bit microcomputer world (Atari 8-bit, C64), and then upgrading to 16-bit (Amiga and PC MS-DOS) I experienced a myriad of unforgettable games on those platforms. They were mostly commercial but they were very much different from modern games. It was the era of innovation and pouring all your soul into the games you produce. I still think that some of them have not been surpassed in quality and playability. I still play them on period correct hardware as they are still extremely fun and challenging.

As I started to play with Linux in the mid 90s I remember a port of Doom and then Quake, but not that many other games. Can you elaborate more on what Unix afficionados played in the late 80s/early 90s?
